CAR-BRAK E.

SPECIFICATION forming part of Letters Patent No. 574,913, dated January.12, 1897.

Application filed February 21,1896. Serial No. 580,234. (No model.)

To all whom it may concern.-

Be it known that I, GEORGE W. LACY, a resident of Kingston, in thecounty of Ulster and State of New York, have invented certain new anduseful Improvements in Car- Brakes; and I do hereby declare thefollowing to be a full, clear, and exact description of theinvention,-sueh as will enable others skilled in the art to which itappertains to make and use the same.

My invention relates to an improvement in oar-brakes, the object beingto provide a simple mechanism of great power which will respond quicklyand accomplish its work effectually; and it consists in certain novelfeatures of construction and combinations of parts, which will behereinafter described,

and pointed out in the claims.

In the accompanying drawings, Figure l is a plan view of a truck,showing my improved brake applied. Fig. 2 is a side elevation.

As the mechanism is the same at both ends, it is only necessary todescribe one set of mechanism.

A is a brake-beam extending across in the usual manner outside of thecar-wheels. To the outer ends of this beam the brake-heads l 1 areconnected, and they are provided with shoes adapted to engage thecar-wheels. A lever 3 is pivoted in each of these brakeheads, and rods4: 4 connect these levers near their pivotal point of connection withthe brake-heads with corresponding levers 3 3 at the opposite end of thecar, the links 5 5 being provided at each end of the rod for connectingit with the levers, so as to give flexibility at this point.

B is the main operating-lever. This lever is pivoted to an arm 6,projecting outward from the brake-beam and located at one side of thecenter of the latter, and connectingrods 7 7, pivotally connected withthe free ends of levers 3 3, are pivotally connected with lever B nearits fulcrum 8. A draft-rod 9 is pivotally connected to the free end ofoperating-lever .B, and to it the power is applied for operating thebrake mechanism.

It will be observed that very little strain comes on the center of thebrake-beam, as heretofore, but the power is transferred to the levers 33. I

It will also be seen that great power is derived from the extensiveleverage and that the action is quick and the parts are responsive.Draft being applied to the rod 9 by means of a brake-Wheel, lever, ordirect pull, the main operating-leverB is caused to swing. In so doingit pulls upon levers3 3, and by virtue of their connection through rods4 4 power is transferred to the brake-heads and they are thrust solidlyagainst the car-wheels.

It is evident that slight changes might be made in the form andarrangement of the several parts described without departing from thespirit and scope of my invention, and hence I do not wish to limitmyself to the ex- .act construction herein set forth; but,

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. In a car-brake, the combination with brake-heads, l, levers 3, 3'pivotally connected therewith, and rods connecting said levers, of leverB fulcrumed on a brake-beam, connections between the brake-head leversand lever B, and means for operating the same, substantially asdescribed.

2. In a car-brake, the combination with a brake-beam, brake-heads,levers pivoted to the brake-heads, at a point directly behind the pointwhere the power is to be applied and rods connected with these leversnear their point of connection with the brakeheads, of a mainoperating-lever fulcrumed on the brake-beam and connecting-rodsextending from the brake-head levers, to the main'operating-levers,substantially as set forth.

3. In a carbrake, the combination with a brake-beam, brake-headsconnected with the ends thereof, levers pivotally connected with saidbrake-heads at a point directly behind the point where the power is tobe applied, links connected with these levers and rods extending fromthe links to the other end of the car, of a main operating-lever,fulcrumed on the brake-beam, and connecting-rods extending from theinner ends of the brakehead levers, to this operating-lever,substantially as set forth.

a. In a car-brake, the combination of a brake-beam, brake-heads, acompound lever system, comprising the levers 3, connections between saidlevers, and lever B, and means 10 tending from the inner ends of levers3, 3 to these main operating-levers and connected with the latter neartheir fnlernms, substantially as set forth.

I11 testimony whereof I have signed this specification in the presenceof two subscribr 5 ing witnesses.

GEORGE \V. LACY.
